I like it too. There are little nitpicks, but I'll just focus on what I like. I like the overall shape of the engineering hull. Really like the pylons, and most of all I like the nacelles. Has a retro feel to them.
That's what I tried to do with my nacelles. I took a lot of inspiration from the Constitution refit nacelles, which in my opinion, are one of the best nacelle designs ever.
Wow, that's... that might be one of the coolest ships I've ever seen. It's got all the features I love about Federation ships. She's sleek and graceful, but still manages to look like she could kick your tail without breaking a sweat. Nice work!
